Description
A nonmirrored cache recovery was attempted but failed to
recover information for any cached LUNs. It does not apply to
a disk array with two SPs.
This disk module has reported a media defect that could not
be cleared by the SP.
The SP encountered multiple errors while attempting to load
the cache image from disk. This message can indicate
multiple drive failures.
The SP found inconsistencies in the cache image on the disk.
This can indicate a failure or abort of the cache dump.
The SP successfully read the control portion of the cache
image on disk, but found the data portion to be incomplete.
This means that a failure or abort occurred during the cache
dump. Probably any LUNs with write-cached pages are
inaccessible and must be rebound. To identify such a LUN,
read message 0x90A in this table.
The SP found the vault disks containing the cache image to
be in a different order than when the cache image was
dumped to disk. This means the disks were swapped at power
down. The disk modules must be restored to their original
order before the SP can load the cache image.
This SP, which is operating in nonmirrored caching mode, has
too low a PROM revision level. Write caching cannot be
enabled.
A RAID-3 LUN cannot be enabled because SP memory
allocated for RAID-3 processing is not available. This can
happen if the disk array is powered up after SP memory has
been removed, or when ownership of the LUN is transferred to
a peer SP that does not have enough memory.
No RAID-3 LUNs can be enabled because SP memory
allocated for RAID-3 processing is not available. This can
happen if the disk array is powered up after SP memory has
been removed, or when the ownership of the LUN is
transferred to a peer SP that does not have enough memory.
The front end Fibre Channel interface failed or is inoperable.
A command failed for the reason explained in the extended
status word.
